Principal Proposed Uses
Other Proposed Uses
Plants need boron for proper health, but it's not known whether humans do. However, boron does seem to assist in the proper absorption of calcium, magnesium, and phosphorus from foods, and slows the loss of these minerals through urination. Very preliminary evidence suggests that boron supplements may be helpful for osteoarthritis and osteoporosis .
SourcesNo dietary or nutritional requirement for boron has been established, and boron deficiency is not known to cause any disease. Good sources include leafy vegetables, raisins, prunes, nuts, non-citrus fruits, and grains. A typical American daily diet provides 1.5 to 3 mg of boron.
Therapeutic DosagesWhen used as a treatment for osteoarthritis or osteoporosis, boron is often recommended at a dosage of 3 mg per day, an amount similar to the average daily intake from food. However, food sources may be safer (see Safety Issues ).
Therapeutic UsesBoron aids in the proper metabolism of vitamins and minerals involved with bone development, such as calcium , copper , magnesium , and vitamin D . 4,10,14-18 In addition, boron appears to affect estrogen and possibly testosterone as well, hormones that affect bone health. 4,10,19 On this basis, boron has been suggested for preventing or treating osteoporosis . However, there have been no clinical studies to evaluate the potential benefits of boron supplements for any bone-related conditions. On the basis of similarly weak evidence, 2,6 boron is often added to supplements intended for the treatment of osteoarthritis. Boron has also been proposed as a sports supplement , based on its effects on hormones. 20 However, studies have, as yet, failed to find evidence that it helps increase muscle mass or enhances performance. 21,22 One large observational study suggests that higher intake of boron may reduce risk of prostate cancer . 5 Finally, boron is sometimes recommended as a treatment for rheumatoid arthritis , but there is no evidence to support this use.
